What Are Cataracts?
Cataracts occur when there is clouding in the lens of the eye resulting in visual impairment. It is a condition that develops slowly and can affect one or both eyes. It contributes to an estimated 33% of global visual impairment and 50% of all cases of blindness.
Most cases of cataracts are due to aging. However, it may also occur because of exposure to radiation or trauma. Past eye surgery or certain health conditions (i.e. diabetes) are other causes of cataracts in adults. Additionally, some genetic conditions can increase the risk of cataracts and they may be present since birth. Finally, the mechanism behind the formation of cataracts is complex and multifactorial.
